“MIDI” stands for ‘Musical Instrument Digital Interface.”’ Practically speaking, it lets you
connect the CPS-300 to other MIDI-equipped musical instruments and devices, such as syn-
thesizers, drum machines, sequencers, and even personal computers.

eConnection to Another MIDI Keyboard

By connecting the CPS-300 to another MIDI keyboard — such
as the Casio VZ-1 — and setting both instruments to the same
MIDI channel, you can use the CPS-300’s keyboard to control
voices created by external sound sources. The external MIDI
instrument can also be used to control the CPS-300. Natural-
ly, the sounds of both keyboards can also be played in ensem-
ble as well.
